American Olean Natural Stone, Quartzite Tile, Slate Collection, Multi-Color, 16x16

A dense fine-grained metamorphic rock, Slate was formed when ancient seabeds, filled with sediments of clay and shale, were pushed upwards by collisions between the continents. It is an extremely durable tile whose beautiful color variations indicate the presence of minerals such as iron oxide. All slate exhibits clear clefting along parallel planes which gives it a unique, streaming texture - a particularly dramatic statement in even the finest of homes.
